To convert 221 seconds to minutes, which ratio could you multiply by?
(Look at image!)
Answers
To convert the seconds into minutes, you'd need to multiply by something that would cancel out the seconds. So if the 221 seconds are the numerator right now, you'd have to multiply by something with the seconds in the denominator.
The only one here that makes sense is
D. 1 minute/60 seconds

Angie is wrapping a present for her best friend. The box is 16 inches long, 12 inches wide, and 3 inches high. How many square inches of wrapping paper does Angie need for her present
Answers
Since we're not looking for the Volume, we'd just multiply one variable by another, for instance:
Bottom = Length * Width
x = 16 * 12 | 16 * 12 = 192
Left = Length * Height
x = 16 * 3 | 16 * 3 = 48
Front = Width * Height
x = 12 * 3 | 12 * 3 = 36
Now that we know 3 of the sides, we then multiply each by 2 since there's another side to this box(in other words, we'd be adding both sides together, multiplying it by 2 still gives you the same answer though).
Bottom + Top, or Bottom * 2
192 + 192 = 384 | or | 192 * 2 = 384
Left + Right, or Left * 2
48 + 48 = 96 | or | 48 * 2 = 96
Front + Back, or Front * 2
36 + 36 = 72 | or | 36 * 2 = 72
Adding these together gives you the answer you're looking for. ^ ^
384 + 96 + 72 = 552
So, the answer should be that Angie needs 552 square inches of wrapping paper for her present. I hope that helped, have a great rest of your day!

Anna buys groceries for her family.hamburger meat is $3.38 per pound sweet potatoes are$0.79. Each and hamburger rolls are $2.30a bag.if Anna buys 3 pounds of meat 5 sweet potatoes and 1 bag of hamburger rolls what will she pay in all for the groceries
Answers
3.38 x 3 = 10.14 for the hamburger meat
.79 x 5 = 3.95 for the sweet potatoes
3.95 + 2.30 + 10.14 = 16.39$ is her total.
To further explain this, and/or to find answers to similar problems like this, you take the amount per pound or whatever unit of measurement (let’s say this variable is Z) and then you take the amount that they are getting per said unit ( let’s say Y) thus an equation that can be used to find problems like this is Z x Y.
The total amount of money paid by Anna is [tex]\fbox{\bf \$16.39}[/tex].
Further explanation:
Given:
Anna buys 3 pounds of hamburger meat.
Anna buys 5 sweet potatoes.
Anna buys 1 bag of hamburger rolls.
The cost of hamburger meat is $3.38 per pound.
The cost of 1 sweet potato is $0.79.
The cost of 1 bag hamburger is $2.30.
Procedure:
1. First find the money spent on hamburger meat, sweet potatoes, and hamburger rolls.
2. Now add all the money to obtain the total money spent on the groceries.
Calculation:
The money spend by Anna on the hamburger meat is obtained as follows:
[tex]\boxed{3.38\times3=\$ 10.14}[/tex]
The money spend by Anna on the sweet potato is obtained as follows:
[tex]\boxed{0.79\times5=\$ 3.95}[/tex]
The money spend by Anna on the hamburger roll is obtained as follows:
[tex]\boxed{2.30\times1=\$ 2.30}[/tex]
Total money spent by Anna to buy all the groceries can be obtained by the sum of the amount of money spent on all the groceries.
Therefore the total money paid by Anna is obtained as,
\boxed{\$ \left( {10.14 + 3.95 + 2.30} \right) = \$ 16.39}.
Thus, the total amount of money paid by Anna is [tex]\fbox{\bf \$16.39}[/tex].

First let's solve for the teacher's:
-2x+5y=10
-3x+9y=6
Solve by substitution (I think elimination might be easier to do for this one, but I don't really remember 100% sorry!)
Isolate the x (or y) variable in the first equation
-2x+5y=10
-2x=10-5y
[tex]x= \frac{10-5y}{-2} [/tex]
Substitute x into the next equation and solve for y
-3(10-5y/2)+9y=6
3*10-5y/2+9y=6
(multiply both sides by 2)
3(10-5y)+18y=12
30-15y+18y=12
30+3y=12
3y=-18
y=-6
Substitute in x
x= -10-5(-6)/2

SELINA'S ANSWER
(8,4)
So neither Goku or Selina got the same answer as the teacher
The teacher's system is
-2x + 5y = 10
-3x + 9y = 6
To find the system that equals to the teachers solution, we must solve all three of them. (Yeah good luck)
Let's start solving the teacher's system
We need to solve -2x + 5y = 10 for x
-2x + 5y = 10
-2x = 10 - 5y
Divide both sides by -2
-2x/-2 = (10-5y)/-2
x = 5/2 y - 5
Now we need to substitute 5/2 y -5 for x in -3x +9y = 6
We gonna replace 5/2 y -5 by x
-3x + 9y = 6
-3(5/2 y - 5) + 9y = 6
Simplify both sides (I used a calculator)
3/2 y + 15 = 6
3/2 y = 6 - 15
3/2 y = -9
To find y, we need to divide both sides by 3/2
3/2 y/3/2 = -9/3/2 (I used a calculator)
y = -6
It easier to find x since we already find y
So, let's find x by substitute -6 for y in x=5/2 y - 5
What does that mean? We gonna replace the value of y which is -6 everywhere we find y (I hope it makes sense)
x = 5/2 y - 5
x = 5/2 (-6) - 5 (use a calculator)
x = -20
Therefor,
x = -20 and y = -6
This is the teacher's solution so we gonna solve the others and see what they have :)
----------------------------------------------
Selina's system
-5x + 14y = 16
-3x + 9y = 12
So, we need to solve -5x + 14y = 16 for x
-5x + 14y = 16
-5x = 16 - 14y
Divide both sides by -5
-5x/-5 = (16 - 14y)/-5
x = 14/5 y + -16/5 (It looks messy here)
To continue, we need to substitute 14/5 y + -16/5 for x in -3x + 9y = 12
-3x + 9y = 12
-3( 14/5 y + -16/5) + 9y = 12
Simplify both sides
3/5 y + 48/5 = 12
3/5 y = 12 - 48/5
3/5 y = 12/ 5
To find y, we just need to divide both sides by 3/5
3/5 y/3/5 = 12/5/3/5 (cancel 5, then divide 12 by 3 = 4)
y = 4
We gonna use the value of y to find x
We gonna do that by substitute 4 for y in x = 14/5 y + -16/5
x = 14/5 y + -16/5
We gonna replace y by 4
x = 14/5 (4) + -16/5 (used a calculator)
x = 8
Therefore,
x = 8 and y = 4
So, Selina system doesn't equal to the teacher's system.
-----------------------------------
Goku's system
again, I used the same steps to solve all of them.
x - 3y = -2
-2x + 5y = -7
We need to solve x - 3y = -2 for x
x - 3y = -2
x = -2 + 3y
I prefer to let the unknown value leads, so it will be
x = 3y - 2 (it still the same thing :) )
Substitute 3y - 2 for x in -2x + 5y = -7
-2x + 5y = -7
-2(3y - 2) + 5y = -7
-6y + 4 + 5y = -7
-y + 4 = -7
-y = -7 - 4
-y = -11
We cannot leave the y with a negative sign, so we must divide both sides by -1
-y/-1 = -11/-1
y = 11
To find x, we need to substitute 11 for y in x = 3y - 2
x = 3y - 2
x = (3)(11)-2
x = 33-2
x = 31
Therefore,
x = 31 and y = 11
Goku's answer doesn't equal to the teacher's answer.

a male lion needs as much as 15 pounds of food each day or 105 pounds of food each week.how much does a lion need in one year.
I'm just checking i have the answer i just want to check thx
Answers
If a male lion eats 15 pounds of food each day or 105 pounds each week, it would need about 5460 pounds of food in a year. We arrive at this by multiplying the weekly amount (105 pounds) by the number of weeks in a year (52 weeks).
Explanation:The question is asking how much food a male lion needs in a year if it eats 15 pounds of food each day, or 105 pounds per week. If we want to know how many pounds of food a lion needs for an entire year, we would need to multiply that weekly amount by the number of weeks in a year. There are 52 weeks in a year. So, we take 105 pounds of food per week and multiply it by 52.
Calculation: 105 × 52 = 5460
So, a male lion needs about 5460 pounds of food in a year.

Convert the following decimal below into a rational number 0.1
Answers
0.1....notice that the 1 is in the tenths place...so put it over 10
0.1 = 1/10 <== ur rational number
It can be expressed as the fraction 1/10, because 0.1 has one decimal place.
The student has asked to convert the decimal 0.1 into a rational number. A rational number is a number that can be expressed as a fraction where both the numerator and the denominator are integers, and the denominator is not zero. To convert a decimal to a rational number, we consider the place value of the decimal. Since 0.1 has one decimal place, it can be expressed as 1/10. Hence, the decimal 0.1 as a rational number is 1/10.
